Design Principle & Project Target
Sedna is an open source distributed key-value storage system based on memory to provide a higher throughput and lower latency R/W operation for real time processing in Cloud. Sedna runs on ZooKeeper - an open source coordinator service, and Memcached, an open source key-value storage system.
Sedna is designed to provide highly available, scalable, and easy deployment service for running data centers. Sedna aims to run on top of an infrastructure of thousands of nodes with abundant memory, built for realtime workloads. At this scale, failure happens continuously, Sedna try to manage the data consistency and persistent state in the face of these failures and gives the softwares the reliability and scalability. While in many ways Sedna resembles ideas from other disk based storage system and shares many design and implementation strategies therewith, Sedna does provide some new features which we believe
